Connecting multiple multichains

Question

Hello, I am after a possible use case that would require the ability to connect between multichains, kind like a mess of blockchains, where you can nlock your transaction in one chain and make it appear in another one. This would be a way to extend capacity by creating sidechains that would contain details that are irrelevant to others. For example, you could have airlines have a chain with their flights and have a separate one with each separate seat in that flight, and another one bundling those seats with additional services, such as car rental or access to business lounge. You could as well issue itineraries in a chain which are a combination of different flights/airlines based on existing seats in other multichains. There are two main benefits of this: allows to separate in a chain business specific permisioning/consensus and second would make multichain scalable.

Does it make sense?

Answer 1

I'm afraid there's no way to directly connect separate blockchains in this way – this would require some kind of combined system in which each of the chains is subordinate to some higher level one.

You can however have trusted intermediaries (or even groups thereof using a multisig) which lock an asset in one chain, and then issue a corresponding asset in another. And then they can do the same in reverse. This is how real-world "side chains" work today.

Thank you very much for the answer, it helps. It makes sense. I will investigate the multisig option combined with a trusted intermediary. Inwas thinking I could use the utxo from one and bring it to the sidechain as inputs and at the same time burning them from the master chain.
Thank you
